How did dark matter form? and is dark energy a result of dark matter like gravity is a result of ordinary matter?
Scientists have observed that the gravitational pull of galaxies is much stronger than can be explained by the visible matter within them. This indicates the presence of an invisible mass, which we call Dark Matter.
The exact composition of Dark Matter is still unknown. It is hypothesized to be made up of particles that do not interact with light, making it invisible to telescopes and difficult to detect.
The formation of Dark Matter is still a mystery. Some theories suggest that it could have formed during the Big Bang, while others propose that it may have been created through the decay of other particles.
Dark Matter plays a crucial role in the formation and evolution of the universe. Its gravitational pull helps to hold galaxies together, and its distribution affects the formation of large-scale structures such as galaxy clusters.
No, Dark Matter cannot be seen directly as it does not interact with light. However, scientists are working on ways to indirectly detect and study Dark Matter, such as through gravitational lensing and particle accelerator experiments.
